Why should anyone care about Evals?
summary
Evals are positioned as more than unit tests: Braintrust builds a dev platform that runs offline experiments to catch faults before deployment, lets teams tweak prompts in a playground, log outputs for observability, and prioritize real-world training data by applying the same metrics from offline to production. The concrete claim is that good evals handle 90% of the product iteration loop before shipping, creating a connected data flywheel that speeds releases and reduces risk.
